HEAT-STORING ATTACHMENT FOR STOVES.

Specification of Letters Patent.

Patented June 21, 1921.

Application filed August 8, 1918. Serial No. 248,941.

Heat-Storing Attachments for Stoves, of

which the following is a specification.

The object of the invention is to provide in connection with heating stoves, a heat storing means located within the stove and 1 above the heat producing element thereof to insure the retentionof the heat, so that the heat may be given off gradually on any reduction of the heat from the fire, such as lowering the fire or decreasing the fuel supply thereof.

The invention accordingly consists in the features of construction, the combination of elements and the arrangement of parts which will be exemplified in the construction hereinafter described and the scope of the application of which will be indicated in the appended claim.

The invention is clearly illustrated in the accompanying drawings, in which:

Figure 1 is a vertical sectional view of the invention applied to a heating stove.

Fig. 2 is a horizontalsection on the line 22 of Fig. l.

Fig. 3 is another horizontal section taken on line 3-3 of Fig. 1. Y

Fig. 4. is a perspective view of the heat containing element.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring now, more particularly, to the accom an in drawin 5 there is 'Jrovided a stove consisting of a body 1 which may be and preferably is supported in spaced re-v lation to a main supporting surface through the instrumentality of legs 2. The body is closed at the bottom while arranged within the body slightly above the bottom is the heating means 3 which may be a gas burner, a coal oil burner, etc. A top .4 is mounted on the stove and may be and met crably is formed with perforations 5 which serve as heat outlets while the walls of the body in proximity to the body are also perforated to provide other heat outlets 6.

WVith a view of providing improved means for insuring the storing or retention of heat in the heating zone of the body of the stove, a heat containing el me t cons u e n the form of a disk 7 is formed desirably of soapstone and is carried against the under surface of the top and is also perforated as at 8 to provide heat passages which aline with the heat outlets 5. Carried against the inner surface of the walls or body of the stove near the cover are a series of suitably spaced bars 9 which act as heat retainers being preferably formed of soapstone. Cooperating with the disk 7 is a heat conducting member 10 which is desirably in the form of a disk and made of copper being'in- 'cidentally' formed with perforations 11 which aline with the perforations 8 to allow some of the heat to pass from the stove. The purpose of the copper disk is to serve as a conductor for quickly absorbing the heat which rises from the heating means and this disk is capable of imparting or conducting heat to the soapstone disk in which the heat is stored or retained to permit of the lowering of the fire without Inaterially decreasing the temperature or heat rising from the stove. The soapstone disk thus acts as a fuel saver. For a similar purpose the bars 9 are provided with heat conducting coverings 12 also formed of copper.

It is believed in view of the foregoing description that a further detailed description is entirely unnecessary. Likewise, it isthought that the advantages of the invent-ion will be readily apparent.

Having thus fully described this invention, what is claimed as new and desired to .be secured by Letters-Patent, is:

The combination with a stove having a hollow body, ofa burnerdisposed within the stove near the bottom thereof, a perforated top closing the body at the upper end, asoapstone disk provided with perforations alining with the perforations in the top, the said disk lying against the latter and being disposed therebeneath, a copper disk lying against the soapstone disk and formed with perforations registering with the perforations in the soapstone disk,

and a plurality of soapstone bars vertically positioned and disposed around the interior surface of the body ad acent to the top and covered with copper, whereby the heat from the burner is communicated to the soapstone 7 disk and bars to be gradually dispensed by the latter, as herein shown and specified.

In testimony whereof I- afiix my signature.

JOHN H. WILSON.
